Argentina missing submarine: Satellite signals detected
Signals have been detected that are thought to have come from an Argentine submarine that went missing with 44 crew on board, officials say.
The defence ministry is now trying to trace the place of the seven failed satellite calls received on Saturday.
Argentina has stepped up the search in the South Atlantic for the ARA San Juan submarine, with a Nasa study plane joining in.
The diesel-electric vessel disappeared 430km (267 miles) off the coast.
Britain and nations in the region have provided assistance. The US Navy is flying deep water rescue modules to Argentina to be deployed if the submarine is found on the sea floor.
The process of the rescuers has been complex by heavy winds and high waves.
The ARA San Juan was returning from a routine mission to Ushuaia, close to the southern-most tip of South America, to its base at Mar del Plata, south of Buenos Aires.
Its last get in touch with with the navy command was on Wednesday morning.
An Argentine destroyer and two corvettes are conducting a search around the region of the sub’s last identified position off the south-eastern Valdez peninsula.
But so far there are no clues about its whereabouts.
It is believed that the submarine might have had communication difficulties caused by a power cut.
Navy protocol dictates that a vessel should come to the surface if communication has been lost.
